Your "invisible frogs" would not be a reformulation of Newtonian Mechanics (NM). A reformulation needs to make the exact same predictions as the original theory. There are many reformulations of both NM and GR, and they are quite useful (and interesting) in various contexts. This is a solid, interesting work that does not deserve being dubbed "horse shit" by a person who does not even have a formal training in the field.
